Frontier Town (Visit this link)

"Experience the thrill" as ya slide down Red Bird’s Mountain, our giant water slide, and splash into the catch pool. Our Lazy River will have ya wishin’ you’d growed fins instead of feet. Designed for kids (with parents in mind) The Waterin’ Hole, our family activity pool, features a huge shallow wadin’ pool with covered wagon mini-slides, cactus fountains, water sprays and more. Best of all, the Water Park is still free to Frontier Town and Fort Whaley campers! Please Note: Maryland State Law requires children must be 42” tall to ride the Giant Waterslide. Acres and acres of FREE PARKIN’, sparklin’ clean bath houses, changin’ rooms and lockers are provided nearby for your convenience.
